Do not lock the register structure in IRQ context. It is not
necessary and leads to lockups under SMP load.

Rename the SoC-specific rtl838x_reg structure in the Ethernet
driver to avoid confusion with the structure of the same name
in the DSA driver. New name is: rtl838x_eth_reg

Setting bits 20 and 23 in a u16 is obviously wrong.
According to https://www.svanheule.net/realtek/cypress/cputag
cpu_tag[2] starts at bit 48 in the cpu-tag structure, so
bit 43 is bit 5 in cpu_tag[2] and bit 40 is bit 8 in
cpu_tag[2].

Set CONFIG_FORCE_MAX_ZONEORDER setting to 13 to allow larger
contiguous memory allocation for the DMA of the Ethernet
driver. Increase the number of entries in the RX ring
to 300 making use of the larger DMA region now possible for
receiveing packets.

Recent versions of Realtek's SDK reset both the ethernet NIC and queues
(SW_NIC_RST and SW_Q_RST bits) when initialising the hardware.
Furthermore, when issuing a CPU reset on the Zyxel GS1900-8 (not
supported by any current driver), the networking part of the SoC is not
reset. This leads to unresponsive network after the restart. By
resetting both the ethernet NIC and queues, networking always comes up
reliably.

This adds support for offloading TC flower by using the Packet Inspection Engine
of the RTL-SoCs. Basic infrastructure support is provide with callbacks to the
tc subsystem and support for HW packet counters.

All RTL SoCs addresss PHYs via their port number, which is mapped to an
SMI address. Add support for configuring this mapping via the .dts on all
SoCs apart from the 839x, where the mapping to the 64 ports is fixed.

On RTL83xx enable learning of the MAC source address of the CPU port
from outgoing packets. Add documentation on bit fields. On RTL93xx
enable port-mask usage and the use of internal priority, these
SoCs automatically learn the MAC.

Remove the storm control and attack warnings from the IRQ handler
of the Ethernet driver. There was no consequence to the detection
and the kernel can also handle at least the attacks itself.

This enlarges the size of the TX ring buffer, which prevents warnings
when the buffer runs out of space.

this patch fixes the following errors when compiling:
- "unsigned int txqueue" is added as an additional parameter of
ndo_tx_timeout in net_device_ops (include/linux/netdevice.h)
- "mac_link_state" in phylink_mac_ops (include/linux/phylink.h)
is renamed to "mac_pcs_get_state" and changed the return value
to void from int
- several parameters are added to "mac_link_up" in phylink_mac_ops
(include/linux/phylink.h) and the order of the parameters is
changed
added:
- int speed
- int duplex
- bool tx_pause
- bool rx_pause
- a parameter "phy_interface_t *interface" is added to of_get_phy_mode
(drivers/of/of_net.c) and returns the state instead of phy mode
